FlashForth is a standalone Forth system for the Microchip PIC 18, 24, 30, 33 and the Atmel Atmega series of microcontrollers. A Forth system with interpreter, compiler, assembler and multitasker is provided.

The OpenSSI project is a comprehensive clustering solution offering a full, highly available SSI environment for Linux. Goals for OpenSSI Clusters include availability, scalability and manageability, built from standard servers.

uSmartx is a non-preemptive, multitasking, priority based kernel for use in embedded designs. Its major features are task and time control over system resources, inter task communication and simple memory management.

OpenMAC is a TinyOS-based implementation of IEEE 802.15.4 MAC layer, which lies at the core of MeshNetics ZigBee stack, and provides basic wireless networking (star,peer to peer) to WSN's. Available for low-power ZigBit modules and Atmel AVR Z-Link Kits

TCPCP2 is the another version of TCPCP(TCP connection passing) which enables TCP /IPv4 session transfer between hosts. The system which requires mission-critical availability typically uses clustering. TCPCP2 enables TCP/IPv4/v6 session take-over.

BOS – B.lu operating System, is an operating system dedicated to small microcontrollers and CPUs without MMU. Actually is dedicated to Texas Instruments MSP430 microcontrollers (it can be ported to other CPUs without great changes)
